A Brony on the Allspark Forums found out something neat about the blind bag ponies that are suddenly appearing everywhere except the US! At least the ones in Hungary.

Each pony is apparently assigned a unique code, meaning these bags aren't as "blind" as originally intended.

*UPDATE* Codes have apparently rolled around ponychan for a while now, here is an image of all of them.

So, instead of buying 30 bags in an attempt to get a fluttershy, you will just need to identify the code for one! Unfortunately, we only have five known codes. The rest will need to be discovered by you non-American bronies!

Thanks to BB-Shockwave from the Allspark Forums for this info! And -treehugger for all of the codes!
